ABSTRACT:
The present invention is directed to a method for manufacturing a dampening roll cover useful in a flat-bed printing process, comprised of hygro-thermally shrinkable fibers which do not shrink due to exposure to ambient mositure during storage. Such dampening roll covers are prepared by preliminarily shrinking a cylinder of a fibrous fleece comprised of hygro-thermally shrinkable fibers to the extent of about 3% to about 50% in length to compact the fibrous structure of the cylinder.
